Appl. No.:

09/776569

International Classification:

E05B 4900

US Classification:

340 52, 342457, 701 35

Abstract:

An access control system prevents a mobile container from being compromised/opened during transit, through the use of a programmable electronic lock, which can be unlocked only by means of an enabled electronic key that has been programmed with geographical location data representative of the destination site of the container. When the mobile container arrives at its destination, the key is coupled with a comparator, which compares the geographic location information in the key with real time geographic location information from a geographic location detection unit associated with the mobile container. In response to a match, the comparator enables the key for a prescribed period of time. The key may then be inserted into the programmable electronic lock, which reads the key to determine whether it has been enabled. If the key is enabled, the lock can be unlocked, to provide access to the container.

International Classification:

G06F 752

US Classification:

364757

Abstract:

A binary multiplier architecture which multiplies signed and unsigned operands as unsigned numbers and adds a correction factor which is the two's complement of the other operand if the operand is signed. The multiplier architecture performs two's complement multiplication when the multiplier has 1's in more than half of its bits and performs unsigned binary multiplication by adding only shifted multiplicand vectors as a function of the multiplier all other times. Two's complement multiplication is performed by adding a multiplicand and a multiplier to two's complemented shifted multiplicand vectors as a function of the two's complement of the multiplier. To reduce the number of additions necessary, portions of the operands are merged with the shifted complemented vectors prior to addition to the shifted vectors.

US Classification:

34082531

Abstract:

A system for controllably actuating a lock mechanism has a lock actuator control unit arranged to receive a key and to communicate with a programmable key control unit contained within the key. The lock actuator control unit contains a power supply for supplying power to the key control unit, so that a transfer of communication signals between the key control unit and the lock actuator control unit may take place. A key is configured to engage the lock actuator control unit, the key containing a programmable key control unit which stores information representative of the ability of the key to cause the lock actuator control unit to actuate the lock mechanism and which receives power for its operation from the lock actuator unit.
